PCB Guidelines for Chip Scale Package
The lands on the chip scale package (CP-20), are rectangular.
The printed circuit board pad for these should be 0.1 mm
longer than the package land length and 0.05 mm wider than
the package land width. The land should be centered on the
pad. This will ensure that the solder joint size is maximized.
The bottom of the chip scale package has a central thermal pad.
The thermal pad on the printed circuit board should be at least
as large as this exposed pad. On the printed circuit board, there
should be clearance of at least 0.25 mm between the thermal
pad and inner edges of the pad pattern. This will ensure that
shorting is avoided.

Thermal vias may be used on the printed circuit board thermal
pad to improve thermal performance of the package. If vias are
used, they should be incorporated in the thermal pad at 1.2 mm
grid pitch. The via diameter should be between 0.3 mm and
0.33 mm and the via barrel should be plated with 1 oz. copper
to plug the via. The user should connect the printed circuit
board pad to AGND.
